1.) The measure of angle k would be = 73°
2.) The value of X would be = 40.
How to calculate the missing angle of the triangle?
To calculate the missing angle of the triangle, the following steps should be taken as follows:
For question 1.)
The total interior angle of a triangle = 180⁰
∠k⁰ = 180-(62+45)
= 180-107
= 73⁰
For question 2.)
Given that;
∠SRT= ∠STR
and ∠STR+∠STU = 180⁰(angle on a straight line)
180⁰ = 20+4x
4x = 180-20
= 160
x = 160/4
= 40.
